100-word summary
Cisco just unveiled the 8223 router—the industry's only fixed 51.2 Tbps platform—powered by its Silicon One P200 chip. Packing 64 ports of 800GE and up to 3 Exabits/second interconnect capacity, it's built to handle massive AI traffic surges between data centers with deep buffering and post-quantum encryption. Shipping first to hyperscalers, it supports open-source SONiC now and IOS XR soon. This positions Cisco as the plumbing provider for distributed AI infrastructure, potentially making it indispensable as companies scale training and inference across multiple data centers.
